## Research

**Projects and collaboration:**

**Causal inference:**

– Causal inference with missing values (with Stefan Wager)

– Transporting causal effect, combining RCT and observational data (with Shu Yang),

– Survival causal inference, sensitivity analyses, policy learning (with Antoine Chambaz)

**Missing values:**

– Missing Non At Random data (with Claire Boyer)

– Supervised Learning with missing values: Random Forests, Neural Nets (with Erwan Scornet, Gael Varoquaux and Marine Le Morvan)

– Variable selection to control the FDR with missing values (with Gosia Bogdan)

– PCA with missing values, multiple imputation, package missMDA (with François Husson)

**Health applications:**

– Handling severe trauma patients, with the Traumabase group, J.P Nadal and Capgemini

– Covid19: Application for bed allocation monitoring/Predict need of intubation/ Effect of hydrochloroquine

**Others:**

– New collaborations: with Jes Frellsen with a grant

– Distributed computation with hospital data (with Balasubramanian Narasimhan)

– Exploratory data analysis (What was the French school of data analysis?)
